4. Speed at any given point in time
8. Measured period of an action unit sec, mh, h
10. The force that oppose that starting motion of the 2 touching surfaces
13. Distance and direction of an objects change in position from starting point
15. When 2 or more forces act on an object at the same time
17. Between a rolling object and it rolls
18. Where 2 surfaces slide past one another
20. Friction in 2 surfaces that are not moving past each other

1. Gravitational force exertion an object
2. Distance an object travels per unit of time, rate of changes in position
3. Friction like force that opposes motion of objects that moves through the air
5. Rate of change of velocity, occurs when object changes speed, direction, or both
6. Occurs when an object changed position relative to a point
7. Anything thrown or shut through the air
9. Includes speed of an object and direction
11. When objects moves through fluid meaning either a liquid or gas
12. How far an object travels
14. Speed that does not change
16. a push or pull to an object
19. Any 2 masses that exert attractive force on eachother
